The New Orleans Police Department announced Wednesday its asking the FBI to review the shooting that left 39-year-old Brian Harris dead on April 9.

Harris' wife, Tyralyn Harris, said she called 911 asking for help. She feared Harris was going to overdose on sleeping pills.

?I said just talk to him. Why do you have assault weapons? I didn't call for him to be killed,? Tyralyn said.

However police said that they were threatened by Harris. According to investigators, Brian barricaded himself inside his bedroom and that one police got inside, Harris was holding a knife and refused to drop the weapon when ordered.

That?s when police said he was shocked with a Taser and shot in the chest.

Attorney Jason Williams is looking for answers to question such as: Why weren't counselors, EMS workers or the Crisis Unit called to the scene?

?Until we deal with rogue cops and aggressive cops, we will continue to have a crime problem,? Williams said.

Harris leaves behind his wife, three young sons and 12 siblings. His family said they have lost faith in police.

?I don't understand. ? All we did is call for help -- help and this is what we get in return,? said Brian?s mother-in-law, Donna Aubert.

The officer involved in the shooting, Stephen McGee, has been reassigned while the investigation is ongoing.

Gen. David Petraeus pleaded guilty to federal charges Tuesday to end a probe into whether he provided classified information to his mistress when he was CIA director, according to a U.S. official briefed on the matter.
